MAS Astro Observing

Members Private Observing Nights


Forest weekends are held close to New Moon. Stargard is held on the second best weekend each cycle and public nights are usually held near First Quarter Moon.

Members must arrange their own transport and bring their own food, drink and warm clothing. It is also essential - for your own safety and that of others - that you bring a red torch with you to observing nights. You should arrive before sunset. Location maps of our observing sites are accessed via the menu at the top of this page.

If arriving late, make sure that your approach to the final gate is with only parking lights and ask someone to guide you safely into the observing area.

If weather conditions look doubtful, please check this page AND the Facebook page AND your Private Messages before leaving home and please ensure you have saved the relevant contact numbers on your mobile phone.


Please consider the needs of others around you, especially when using laser pointers, camera and computer monitors, car boot and interior lights etc. Please read our Field Etiquette page from the menu at the top of this page.

Stargard Observing


Stargard nights at The Oaks (adjacent to The Oaks Airport) are free to financial members and invited guests only. Please contact the President before inviting non-members to attend.

Beginners are particularly encouraged to observe at Stargard before progressing to the Forest. Members who have not yet purchased a telescope and  wish to familiarise themselves with what other members use are welcome to attend and seek advice from more experienced members.

Stargard observing dates are scheduled for one Saturday of each Lunar cycle, either the week before The Forest or the week after.

If a scheduled night is cancelled due to weather, another night may be selected.


Members are requested to always close the main gate and throw the bolt without locking it, to discourage entry by non-authorised people but permit entry or egress by members.

The Forest Observing

The Forest Cabin Under the Stars, copyright Tony Law  

The cabin at Belanglo Forest is our premier dark-sky observing site, normally open on the Weekend closest to the New Moon. Bring your equipment and observe or photograph our Forest sky which really has to be seen to be believed on a clear night. Limited sleeping accommodation is available but depending on the numbers is not guaranteed.

Non-members who are experienced amateur astronomers may be invited to attend the Forest, subject to prior clearance from the President.

Use of the site between Sunday morning and Monday morning will be dependent on the number of members each month who express a desire to attend. Members who have paid for two nights will get the third night free. 

Forest Charge for members: $20 for one night, $35 for two nights, third night free (per member), whether attending just for the evening or staying all night. Please see Ned Pastor or Tony Law on your arrival to make your payment and please try to have the exact amount. 

Charge for invited non-members: $25.00 for one night and $45.00 for two nights, third night free.

Free weekend: each financial member is entitled to one free Forest weekend per year. Bring your current membership card with you when you come to a New Moon Weekend and it will be punched, signifying that you've taken your free weekend.
